"Hey, is your name 'Mitt'? Then the Late Show wants you to be a part of our 'Night of a Thousand Mitts.' Just send a 3X5 card to: 'Hey, I'm Mitt c/o The Late Show, 1697 Broadway, New York, New York 10019. Good luck, and get Mitting!"
Remember, this is the late-night show that has writers. And "3X5 card"? What about the Interweb? Don't Mitts have access to that? (Bill Frost)
